Probably a stupid question, but I just got my 2010 SS and am wondering what the clicking sound is that I hear after I turn off my engine? There's a loud click and sometimes a fainter second one. It seems to come from under the hood. Does it have something to do with the turbo?

 

Throttle body going from fully shut kill position to it's neutral position.

 

sometimes ive noticed on mine there is clicking constantly for about 3 minutes i believe its the coolant

 

Bingo!

 

really? cause it honestly sounds like a ping pong ball being dropped down a plastic tube. And it makes a high pitched beep.

I dont know if I can trust answers from 3 people who dont even own an SS/TC I know my 2.2 never made this noise and i always found it weird and glad OP made this thread

 

Mine makes the exact noice... the ping pong ball is the exact description of the sound too... i have an 09 sedan and its made that sound since day one... its a quiet high pitch beeeeeeeeep then click clikk... i never knew what it was....

 

One can only guess with the description given!!

The way he described it to me reminds me of when my TB goes to the closed position.

 

Some of the noises are also relays turning off, such as the ones for the headlights.

 

I will have to turn off my radio and listen next time, may even just go out and try it..

 

It's the throttle body. Open your hood and have someone turn the car off if you're doubtful about it

 

Part of that may be because the LNF doesn't have the engine shroud to muffle noises and you may not have had the underhood blanket that is standard on older 2.2's.

 

I'm so stupid because I don't own a Cobalt.
